A capacitor of capacitance C=2.0±0.1μF is charged to a voltage V=20±0.2V. What will be the charge Q on the capacitor? Use Q=CV
In the circuit shown below, initially the switch S1 is open, the capacitor C1 has a charge of 6 coulomb, and the capacitor C2 has 0 coulomb. After S1 is closed, the charge on C2 in steady state is Coulomb.
Two point charges 3×10−6C and 8×10−6C repel each other by a force of 6×10−3N. If each of them is given an additional charge −6×106C, the force between them will be
